What is the difference between the following multilink ppp configuration, when would u use one and not the other (from cisco website)
The following example shows how to configure MRRU negotiation on a virtual template with synchronous serial interfaces. The example also applies to asynchronous serial interfaces.
multilink virtual-template 1 ! interface virtual-template 1 ip address 10.13.1.1 255.255.255.0 mtu 1600 ! interface serial 0/0 ppp multilink ppp multilink mrru local 1600 mtu 1600 ! interface serial 0/1 ppp multilink ppp multilink mrru local 1600 mtu 1600 PPP/MLP MRRU Negotiation Configuration on Multilink Groups: Example The following example shows how to configure MRRU negotiation on multilink groups:
interface multilink 10 ip address 10.13.1.1 255.255.255.0 ppp multilink mrru local 1600 mtu 1600 ! interface serial 0/0 ppp multilink multilink-group 10 mtu 1600 ! interface serial 0/1 ppp multilink multilink-group 10 mtu 1600
